A buccal swab, also known as buccal smear, is a way to collect DNA from the cells on the inside of a person's cheek. Buccal swabs are a relatively non-invasive way to collect DNA samples for testing .
The cheek is the most common location from which a DNA sample can be taken. (Some saliva is collected from inside the mouth, e.g. using a cotton-tipped rod called a swab or "Q-Tip". The procedure of collecting a sample in that way is typically called a "cheek swab".)
Candidiasis is a fungal infection due to any species of the genus Candida (a yeast). [4] When it affects the mouth, in some countries it is commonly called thrush. [3] Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. [3]
Then it is placed under a microscope and a positive result is the visualization of dark red, feathery crystals. [3] For the immunochromatographic test, it functions similar to a pregnancy test where antigens present in blood are detected and a positive result is a band at the test site and control site. [ 9 ]
Phase contrast microscopy of clue cells in a vaginal swab A pH indicator to detect vaginal alkalinization (here showing approximately pH 8), and a microscope slide to microscopically detect clue cells Gram stain of cells from the vagina (the same magnification) with normal bacterial flora (top) and the bacteria that cause vaginosis (bottom).
Under this form of testing, the blood types of the child and parents are compared, and it can be determined whether there is any possibility of a parental link. For example, two O blood type parents can produce a child only with an O blood type, and two parents with a B blood type can produce a child with either a B or an O blood type.
Cocci is an English loanword of a modern or Neo-Latin noun, which in turn stems from the Greek masculine noun κόκκος (cóccos) meaning 'berry'. [ 6 ] Important human diseases caused by coccoid bacteria include staphylococcal infections, some types of food poisoning , some urinary tract infections , toxic shock syndrome , gonorrhea , as ...
Gram stain of Candida albicans from a vaginal swab. The small oval chlamydospores are 2–4 μm in diameter. Gram staining is a bacteriological laboratory technique [ 8 ] used to differentiate bacterial species into two large groups ( gram-positive and gram-negative ) based on the physical properties of their cell walls .
